ROOFERS SEAMIN'G-TOOL.

SPECIFICATION forming part of Letters Patent No. 541,087, dated June 18, 18 95.

Application filed April 28, 1894. Serial No. 509,393- (No modeLl To all whom it may concern:

Be it known that we, WILLIAM L. HEBER- LING and HENRY HEBERLING, citizens of the United States, residing at Havana, in the county of Mason and State of Illinois, have invented new and useful Improvements in Roofers Seaming-Tools, of which the following is a specification. r

Our invention relates to tools for forming both single-lock and double-look standing seams in metal roofing, and has for its object to provide a simple, inexpensive tool that will perform all the operations of double-seaming efficiently, by the outward movement of two common handles, dispensing with foot power and the use of a second tool to complete the To accomplish this object by the use of the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a perspective of our tool resting on its base with its jaws open. Fig. 2 is an end view of it with'its raising-frame swung out from under it and its jaws closed against a seam. Fig. 3 shows a part of our mechanism for locking the raising-frame on its hinge. Fig. 4 is a rear View of the tool in elevation, showing a part of the hinge of the raising frame cut away. 7

This tool is very simple, consisting mainly of a stationary under jaw over the edge ofwhich the metal is folded, and an upper jaw which is hinged to work in opposition with it, both supported on, a base plate, together with a raising frame which works underneath the base plate, or may be swung out therefrom to let the tool down.

The base plate 1, is connected by arches, 2, 2, with the under jaw 3, all of which are rigid with the handle 4, Figs. 1 and 2. The upper jaw 5, hinged by lugs 5' 5 on the hinge pin connected by the link 6, to the han'dle 6, which is hinged'between the lugs 4, and operates it, Figs. 1 and 2. Beneath the base plate 1, Figs. 1 and 4, is theraising frame 7, which may be swung out from under the tool to let it down as in Fig. 2.. This frame is hinged on the rod 8, which passes through it and the supports 2' which extend from the arches 2, Figs. 1, 2 and 4. It is provided near its hinges with side projections 7, 7', Figs. 1,

2, 3, and 4, which extend over and neatly engage the edges of the supports 2", 2', as in Figs. 2, 3 and 4, so as to limit its swing on its hinge and lock it in either of the positions shown in Figs. 2 and 3. It will be noticed that the frame 7, is hinged at the side of the supports 2, 2, and has room to play endwise on the hinge rod 8, Fig. 4. This rod, however, is surrounded by a compressed spiral spring with one end pressing against the support 2, and the other pressing against the frame, Fig. 4, which tends to hold the side ex tensions 7', 7, of the frame over the edges of the supports 2, 2, where the former neatly engage the shoulders of the latter and sup port the frame in either of the positions shown in Figs. 2 and 3. To release the frame the operator forces it endwise far enough to disengage the parts described, which permits it to be swung from one position to the other,in either of which it will automatically lock itself as before. supptemented by the catch 7", on one end of the raising frame, which acts simultaneously with it, and engages the base plate near its corner in the action described, holding it more firmly in working position, Figs. 1 and 4.

To operate the tool it is placed with handleserect astride the seam flanges with the base plate on the sheet having the taller or un cleated flange. The handle 4, is then inclined to about forty five degrees bringingthe under jaw in place against the side of the shorter or cleated flange. The handle 6, is then forced out bending the metal over the edge of the under jaw 3, which completes the first operation of the tool. When this operation is performed the tool is reversed in its position on the seam and used as a clamp, completing the first fold in the seam. In double-seaming the above process is first gone through with the raising frame under the tool, as in Figs.

'1 and 4, and. then with the tool reversed and the raising frame swung up in idle position, as in Fig.2, the process is repeated.

In this tool we have combined simplicity with efficiency, dispensing with many parts and utilizing remaining ones to a high degree. By resting the tool on one side only, we hold down the nucleated flange and are enabled to release the under jaw from metal bent over it This locking mechanism is past a right angle. This enables us to use the bending jaws as clamps to-close the fold, and do all with the outward movement of two handles; and in the use of the raising frame we double the utility of the parts.

that we claim as new, and desire to secure by Letters Patent, is

1. In a roofers seaming tool, a base plate and an under jaw in rigid position with each other and adapted to receive the flanges of a standing seam between them, in combination with an upper jaw which is hinged or pivoted therewith above the body of said under jaw.

2. In a roofers seaming too1,abase plate and an under jaw in rigid position with each other and adapted to receive the flanges of a standing seam between them, in combination with an upper jaw which is hinged or pivoted therewith above the body of said under jaw and is provided with two lips one of which is adapted to pass over the edge and the other of which is adapted to work against the perpendicular face of said under jaw.

3. In aroofers seaming tool,a base plate and an under jaw in rigid position with each other and adapted to receive the flanges of a standing seam between them, in combination with an upper jaw which ishinged or pivoted there with above the body of said under jaw; and a raising frame or bar which is adapted to work under said base plate.

4. In a roofers seaming tool, a'base plate and an under jaw in rigid position with each other and adapted to receive the flanges of a standing seam between them, in combination with an upper jaw which is hinged or pivoted there with above the body of said under jaw; and ahinged raising, frame or bar which is adapted to fold underneath said base plate or to be.

swung out therefrom and is provided with an automatic locking device.

5. In a roofers seaming tool, an upper jaw which is provided with two rigid lips one of which is adapted to pass over the edge and the other of which is adapted to work against the perpendicular face 0t an under jaw with which it is connected bya single hinge or pivotal joint above the body of said under jaw, in combination with means of support adapted to sustain the tool at a proper height and to rest near and hold down the talleror nucleated flange of the seam while the tool is forming its initial bend; all operated by two handles. 6. In a roofers seaming tool, an upper jaw which is provided with two lips one of which is adapted to pass over the edge and the other of which is adapted to work against the perpendicular face of an underjaw with which it is connected by a single hinge orpivotal joint above the bodyof said underjaw, in combination with a raising frame or plate which is adapted to sustain the tool at a proper height and to rest near and hold down the taller or uncleated flange of the seam while the tool is forming its initial bond.

7. In a roofers seaming tool, an upper jaw which is provided with two lips one of which is adapted to pass over the edge and the other of which is adapted to work against the perpendicular face of an nnderjjaw with which it is connected by a single hinge or pivotal joint above the body of said under jaw, in combination with a hinged raising frame or plate which is adapted to raise the tool temporarily and to rest near and hold down the taller or nucleated seam flange while the tool forms its initial bend, and to be swung out from under the tool to let it down, and is provided with an automatic lock which operates by an endwise movement of the frame and holds it in proper position.

8. In a roofers seaming tool, an upper jaw which is provided with two lips one of which is adapted to pass over the edge and the other of which is adapted to work against the perpendicular face of an under jaw with which it is connected by a single hinge or pivotal joint above the body of said under-jaw, in combination with means of support which are adapted to rest near and to hold down the taller or uncleated flange of the seam while its initial bend is being formed by the tool, all adapted to be operated by two handles; and with a hinged raising frame or bar which is adapted to work under said means of support or to be swung out therefrom and is provided with a lock or catch to hold it in position.
